Question

Match the following mixtures with their appropriate method of separation.

• A. Evaporation
• B. Sublimation
• C. Centrifugation

Answer 1

Evaporation is a process which separates a volatile component from a non-volatile component in a mixture. Example- In salt and water mixture, water is a volatile component and salt is non-volatile. So, water gets separated from salt by evaporation.

Sublimation is a process which separates sublimable component from a non-sublimable component in a mixture. Example- A mixture of salt and camphor can be separated by sublimation, as the camphor will undergo sublimation and salt will be left behind.

Centrifugation is a process of separation of colloidal particles using a centrifuge. This happens because of the difference in densities of colloidal components. Example- Drugs in blood can be separated using centrifugation.
